Choosing Colours for Summer Workwear

Choosing Colours for Summer Workwear: Heat-Reducing Colours and Their Psychological Effects

When the summer months arrive, the biggest problem faced by staff working in factories, on construction sites and in supermarket chains is heat and comfort. Employees carry out intense physical activity for 8-10 hours a day, and an unsuitable choice of workwear can reduce productivity by 15-25%.

However, many companies look only at fabric quality when choosing summer workwear. They overlook the effect that colour choice has on heat, comfort and employee psychology.

In this article, we explain how colour choice in summer workwear reduces heat, its psychological effects and the right colour strategy for companies with 100+ employees.

1. The Physics of Colour: Heat-Reducing Colours

Light Reflection and Colour Absorption

Colour results from a surface reflecting or absorbing different parts of the wavelength of light. This has a direct effect on heat.

Basic Principle:

•Light colours (white, yellow, light blue): Reflect light and reduce heat

•Dark colours (black, dark blue, grey): Absorb light and increase heat

Scientific Data

Research shows that:

•White clothing: Reduces temperature by 5-8°C

•Light blue clothing: Reduces temperature by 3-5°C

•Light green clothing: Reduces temperature by 2-4°C

•Dark blue clothing: Increases temperature by 1-2°C

•Black clothing: Increases temperature by 3-5°C

Practical Example

Scenario: A factory environment at 35°C

•White clothing: Effective temperature ~27-30°C

•Light blue clothing: Effective temperature ~30-32°C

•Dark blue clothing: Effective temperature ~36-37°C

Result: White clothing feels 6-10°C cooler than dark blue clothing!
